| 摘 要： | 本文以田间试验和生长箱内的模拟试验资料，分别讨论了土壤－植物系统（含冬小麦和玉米）中稳态水流阻力和瞬态水流阻力的差别，结果指出，在瞬变环境条件下，用稳态流来近似是不准确的，瞬态流的描述应受重视。

| Abstract: | Based on the experimential data obtained from winter wheat and corn in field and growth box, the differences of hydraulic resistance between steady water flow and unsteady water flow in the soil winter wheat and soil-corn system were studied in this work. The results indicated that under unsteady environmental conditions the model of steady water flow was not accurate, but, instead, the model of unsteady water flow should be valued. |
